Did the author make the opposite point? (I'm having trouble seeing it if he did. For example, the sentence that follows what you quoted exemplifies the author's efforts to not define morality in strict terms: "However, we [engineers] are part and parcel of industrial modernity with all its might, advantages and flaws, and we therefore contribute to human suffering as well as flourishing.")
